I had 2 of these 70w HPS running for a short while. I liked what they did. I also had CFLs going too. At the time I had maybe 4 small plants (12-18 inches). I soon after ordered a 400w HPS, though.
I was thinking about doing a separate grow using 1 70w HPS and 1 plant with some training techniques. But, that might be a while.
For the cost of these 70w fixtures with everything you need to get them going and hung up -- fixture, power cord, chains, fasteners, you are much better off ordering a 400w or more HPS.
I should have just paid the ~$140 for the 400w at first rather than spend ~$220 on buying the 70w + everything else.
